Heavy Duty Hot DIP Galvanized Steel Bar Grate Floor Grating

Hot Dipped Galvanized Heavy Duty Steel Grating 70mm x 6mm Bearing Bar

Welded Heavy Duty Gratings are designed to service applications subject to heavy rolling and static loads such as highways, plant floors, loading docks, inlet covers and airports. Since these conditions can range from light-duty forklifts to heavy-duty truck or aircraft traffic, heavy duty gratings are manufactured in a wide range of bar sizes and spacings. Our most popular products are described on the following pages.

Materials & Finishes

Heavy duty gratings are manufactured in carbon steel and 300 series stainless steels. Carbon steel products are available bare (no finish), painted with manufacturers standard paint, or hot dip galvanized. Stainless steel products are available mill finish, commercially cleaned or electro-polished.

Table of Spacings

Banding

Heavy duty gratings are commonly subjected to shock and impact loads and it is highly recommended that all open ends be banded. The welded band bar helps distribute impact loads and minimizes distortion when subjected to repetitive traffic patterns. Banding details can be found under

Serrated Surface

Optional serrated bearing bars enhance skid resistance. Consider this surface for applications subject to the accumulation of liquids or lubricants or inclined grating installations.

GNEE Steel Grating Application

Steel grating are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering.

• Hot dip galvanized steel grating is the best choice for steel platforms in airports. Grating with 30 × 3 mm thick load bearing bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is the suitable one.
• Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. It can be used for ceiling, interior decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
• Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on.
